2. Description of the Related Art

In recent years, with the rise of portable electronic devices havingcamera functionalities, the demand for an optical image capturing systemhas gradually been raised. The image sensing device of the ordinaryphotographing camera is commonly selected from a charge coupled device(CCD) or a complementary metal-oxide semiconductor sensor (CMOS Sensor).Also, as advanced semiconductor manufacturing technology enables theminimization of the pixel size of the image sensing device, thedevelopment of the optical image capturing system has gravitated towardsthe field of high pixels. Therefore, the requirement for high imagequality has been rapidly increasing.

The traditional optical image capturing system of a portable electronicdevice comes with different designs, including a four-lens or afive-lens design. However, the requirement for the higher pixels and therequirement for a large aperture of an end user, like functionalities ofmicro filming and night view, or the requirement of wide angle of viewof the portable electronic device have been raised, thus the opticalimage capturing system in prior arts cannot meet the requirement of thehigher order camera lens module.

Therefore, how to effectively increase quantity of incoming light of theoptical lenses, and further improve image quality for the imageformation, has become an important issue.

The transverse aberration of the margin of the aperture may be expressedas STA and evaluates the performance of the specific optical imagecapturing system. The transverse aberration at any field of view may becalculated by utilizing the tangential fan and the sagittal fan.Specifically, the transverse aberration at the longest operationwavelength (for instance, the wavelength is 650 nm) and the shortestoperation wavelength (for instance, the wavelength is 470 nm)respectively passing through the margin of the aperture is calculated toact as the standard of the performance. The aforementioned coordinatedirection of the tangential fan can be further divided into the positivedirection (the upper ray) and the negative direction (the lower ray).The transverse aberration at the longest operation wavelength passingthrough the margin of the aperture defines the difference between theimage position at the specific field of view where the longest operationwavelength passes through the margin of the aperture and strikes on thefirst image plane and the image position at the specific field of viewwhere the chief ray of the reference wavelength (for instance, thewavelength is 555 nm) strikes on the first image plane.

Evenfurther, the way of the examination can be that the transverseaberration at the 0.7 field of view where the longest operationwavelength passes through the margin of the aperture and strikes on thefirst image plane and the transverse aberration at the 0.7 field of viewwhere the shortest operation wavelength passes through the margin of theaperture and strikes on the first image plane are both less than 80 μm.

The arc length of any surface of a single lens within the maximumeffective half diameter affects the surface's ability to correct theaberration and the optical path differences between each of the fieldsof view. The longer the arc length is, the better the ability to correctthe aberration will be. However, difficulties may be found in themanufacturing process. Therefore, it is necessary to control the arclength of any surface of a single lens within the maximum effective halfdiameter, especially the ratio (ARS/TP) between the arc length (ARS) ofthe surface within the maximum effective half diameter and the thickness(TP) of the lens to which the surface belongs on the optical axis. Forinstance, ARS11 denotes the arc length of the maximum effective halfdiameter of the object side surface of the first lens. TP1 denotes thethickness of the first lens on the optical axis. The ratio between thetwo is ARS11/TP1. ARS12 denotes the arc length of the maximum effectivehalf diameter of the image side surface of the first lens. The ratiobetween ARS12 and TP1 is ARS12/TP1. ARS21 denotes the arc length of themaximum effective half diameter of the object side surface of the secondlens. TP2 denotes the thickness of the second lens on the optical axis.The ratio between the two is ARS21/TP2. ARS22 denotes the arc length ofthe maximum effective half diameter of the image side surface of thesecond lens. The ratio between ARS22 and TP2 is ARS22/TP2. The ratiobetween the arc length of the maximum effective half diameter of anysurface of the rest lenses in the optical image capturing module and thethickness (TP) of the lens to which the surface belongs on the opticalaxis may be deducted on this basis.

The arc length of any surface of a single lens within the height of halfthe entrance pupil diameter (HEP) particularly affects the surface'sability to correct the aberration and the optical path differencesbetween each of the fields of view at the shared area. The longer thearc length is, the better the ability to correct the aberration will be.However, difficulties may be found in the manufacturing process.Therefore, it is necessary to control the arc length of any surface of asingle lens within the height of half the entrance pupil diameter (HEP),especially the ratio (ARE/TP) between the arc length (ARE) of thesurface within the height of the half the entrance pupil diameter (HEP)and the thickness (TP) of the lens to which the surface belongs on theoptical axis. For instance, ARE11 denotes the arc length of the heightof the half the entrance pupil diameter (HEP) of the object side surfaceof the first lens. TP1 denotes the thickness of the first lens on theoptical axis. The ratio between the two is ARE11/TP1. ARE12 denotes thearc length of the height of the half the entrance pupil diameter (HEP)of the image side surface of the first lens. The ratio between ARE12 andTP1 is ARE12/TP1. ARE21 denotes the arc length of the height of the halfthe entrance pupil diameter (HEP) of the object side surface of thesecond lens. TP2 denotes the thickness of the second lens on the opticalaxis. The ratio between the two is ARE21/TP2. ARE22 denotes the arclength of the height of the half the entrance pupil diameter (HEP) ofthe image side surface of the second lens. The ratio between ARE22 andTP2 is ARE22/TP2. The ratio between the arc length of the height of thehalf the entrance pupil diameter (HEP) of any surface of the rest lensesin the optical image capturing module and the thickness (TP) of the lensto which the surface belongs on the optical axis may be deducted on thisbasis.

The height of optical system (HOS) may be reduced to achieve theminimization of the optical image capturing system when the absolutevalue of f1 is larger than f6 (|f1|>|f6|).

When |f2|+|f3|+|f4|+|f5| and |f1|+|f6| meet the aforementionedconditions, at least one lens among the second lens to the fifth lensmay have a weak positive refractive power or a weak negative refractivepower. The weak refractive power indicates that an absolute value of thefocal length of a specific lens is greater than 10. When at least onelens among the second lens to the fifth lens has the weak positiverefractive power, the positive refractive power of the first lens can beshared by this configuration, such that the unnecessary aberration willnot appear too early. On the contrary, when at least one lens among thesecond lens to the fifth lens has the weak negative refractive power,the aberration of the optical image capturing system can be slightlycorrected.

Besides, the sixth lens may have negative refractive power, and theimage side thereof may be a concave surface. Hereby, this configurationis beneficial to shorten the back focal length of the optical imagecapturing system so as to keep the optical image capturing systemminimized. Moreover, at least one surface of the sixth lens may possessat least one inflection point, which is capable of effectively reducingthe incident angle of the off-axis rays, thereby further correcting theoff-axis aberration.

In one embodiment of the optical image capturing system of the presentinvention, the chromatic aberration of the optical image capturingsystem can be corrected by alternatively arranging the lenses with largecoefficient of dispersion and small coefficient of dispersion.

The equation for the aspheric surface as mentioned above is:

wherein, z is the position value of the position along the optical axisat the height h where the surface apex is regarded as a reference; k isthe conic coefficient; c is the reciprocal of curvature radius; and A4,A6, A8, A10, A12, A14, A16, A18, and A20 are high order asphericcoefficients.

In the optical image capturing module provided by the presentdisclosure, the material of the lens may be made of glass or plastic.Using plastic as the material for producing the lens may effectivelyreduce the cost of manufacturing. In addition, using glass as thematerial for producing the lens may control the heat effect and increasethe designed space configured by the refractive power of the opticalimage capturing module. Moreover, the object side surface and the imageside surface from the first lens to the sixth lens may be a spheric,which may obtain more control variables. Apart from eliminating theaberration, the number of lenses used may be reduced compared with thatof traditional lenses used made by glass. Thus, the total height of theoptical image capturing module may be reduced effectively.

Furthermore, in the optical image capturing system provided by thepresent invention, when the surface of the lens is a convex surface, thesurface of the lens adjacent to the optical axis is convex in principle,and when the surface of the lens is a concave surface, the surface ofthe lens adjacent to the optical axis is concave in principle.

The optical image capturing system of the present invention can beapplied to the optical image capturing system with automatic focus basedon the demand and has the characteristics of good aberration correctionand good image quality. Thereby, the optical image capturing systemexpands the application aspect.

The optical image capturing system of the present invention can furtherinclude a driving module based on the demand. The driving module may becoupled with the lens and enable the movement of the lens. The foregoingdriving module may be the voice coil motor (VCM) which is applied tomove the lens to focus, or may be the optical image stabilization (OIS)which is applied to reduce the frequency which lead to the out focus dueto the vibration of the camera lens in the shooting process.

At least one of the first lens, the second lens, the third lens, thefourth lens, the fifth lens and the sixth lens of the optical imagecapturing system of the present invention may further be designed as alight filtering element with a wavelength of less than 500 nm based onthe demand. The light filtering element may be made by coating film onat least one surface of that lens with certain filtering function, orforming that lens with material that can filter light with shortwavelength.

The image plane of the optical image capturing system of the presentinvention may be a plane or a curved surface based on the designrequirements. When the image plane is a curved surface (e.g. a sphericalsurface with curvature radius), the decrease of the required incidentangle to focus rays on the image plane is helpful. In addition to theaid of the miniaturization of the length of the optical image capturingsystem (TTL), this configuration is helpful to elevate the relativeillumination at the same time.

Fourth Embodiment

Please refer to FIGS. 4A to 4C. FIG. 4A is a schematic view of theoptical image capturing system according to the fourth embodiment of thepresent invention. FIG. 4B is a curve diagram illustrating the sphericalaberration, astigmatism and optical distortion of the optical imagecapturing system in order from left to right according to the fourthembodiment of the present invention. FIG. 4C shows the sagittal fan andthe tangential fan of the optical image capturing system and the lateralaberration diagram of the longest operation wavelength and the shortestoperation wavelength passing thorough the margin of the aperture at 0.7field of view according to the fourth embodiment of the presentinvention. As shown in FIG. 4A, an optical image capturing system 40includes, in the order from the object side to the image side, a firstlens 410, a second lens 420, an aperture 400, a third lens 430, a fourthlens 440, a fifth lens 450, a sixth lens 460, an IR-cut filter 480, animage plane 490, and an image sensor element 492.

The first lens 410 has positive refractive power and is made of plastic.The object side 412 of the first lens 410 is a concave surface and theimage side 414 of the first lens 410 is a convex surface, and the objectside 412 and the image side 414 are aspheric. The object side 412 hasone inflection point and the image side 414 has one inflection point.

The second lens 420 has positive refractive power and is made ofplastic. The object side 422 of the second lens 420 is a convex surfaceand the image side 424 of the second lens 420 is a concave surface.

The third lens 430 has positive refractive power and is made of plastic.An object side 432 of the third lens 430 is a concave surface and animage side 434 of the third lens 430 is a convex surface, and the objectside 432 and the image side 434 are both aspheric.

The fourth lens 440 has negative refractive power and is made ofplastic. An object side 442 of the fourth lens 440 is a concave surfaceand an image side 444 of the fourth lens 440 is a concave surface, andthe object side 442 and the image side 444 are both aspheric. The objectside 442 has one inflection point, and the image side 444 has twoinflection points.

The fifth lens 450 has positive refractive power and is made of plastic.An object side 452 of the fifth lens 450 is a concave surface and animage side 454 of the fifth lens 450 is a convex surface, and the objectside 452 and the image side 454 are both aspheric. The object side 452has one inflection point and the image side 454 has one inflectionpoint.

The sixth lens 460 has negative refractive power and is made of plastic.An object side 462 of the sixth lens 460 is a convex surface and animage side 464 of the sixth lens 460 is a concave surface, and theobject side 462 and the image side 464 are both aspheric. The objectside 462 has two inflection points and the image side 464 has oneinflection point. Hereby, this configuration is beneficial to shortenthe back focal length of the optical image capturing system so as tokeep the optical image capturing system minimized. Furthermore, theincident angle of the off-axis rays can be effectively reduced, therebyfurther correcting the off-axis aberration.

The IR-cut filter 480 is made of glass, and disposed between the sixthlens 460 and the image plane 490, and does not affect the focal lengthof the optical image capturing system.

Sixth Embodiment

Please refer to FIGS. 6A to 6C. FIG. 6A is a schematic view of theoptical image capturing system according to the sixth embodiment of thepresent invention. FIG. 6B is a curve diagram illustrating the sphericalaberration, astigmatism and optical distortion of the optical imagecapturing system in order from left to right according to the sixthembodiment of the present invention. FIG. 6C shows the sagittal fan andthe tangential fan of the optical image capturing system and the lateralaberration diagram of the longest operation wavelength and the shortestoperation wavelength passing thorough the margin of the aperture at 0.7field of view according to the sixth embodiment of the presentinvention. As shown in FIG. 6A, an optical image capturing system 60includes, in the order from the object side to the image side, a firstlens 610, a second lens 620, an aperture 600, a third lens 630, a fourthlens 640, a fifth lens 650, a sixth lens 660, an IR-cut filter 680, animage plane 690, and an image sensor element 692.

The first lens 610 has positive refractive power and is made of plastic.The object side 612 of the first lens 610 is a concave surface and theimage side 614 of the first lens 610 is a convex surface, and the objectside 612 and the image side 614 are aspheric. The object side 612 hasone inflection point, and the image side 614 has one inflection point.

The second lens 620 has positive refractive power and is made ofplastic. The object side 622 of the second lens 620 is a convex surfaceand the image side 624 of the second lens 620 is a concave surface, andthe object side 622 and the image side 624 are aspheric. The image side624 has two inflection points.

The third lens 630 has positive refractive power and is made of plastic.An object side 632 of the third lens 630 is a concave surface and animage side 634 of the third lens 630 is a convex surface, and the objectside 632 and the image side 634 are both aspheric.

The fourth lens 640 has negative refractive power and is made ofplastic. An object side 642 of the fourth lens 640 is a concave surfaceand an image side 644 of the fourth lens 640 is a concave surface, andthe object side 642 and the image side 644 are both aspheric. The objectside 642 has one inflection point, and the image side 644 has twoinflection points.

The fifth lens 650 has positive refractive power and is made of plastic.An object side 652 of the fifth lens 650 is a concave surface and animage side 654 of the fifth lens 650 is a convex surface, and the objectside 652 and the image side 654 are both aspheric. The object side 652has one inflection point and the image side 654 has one inflectionpoint.

The sixth lens 660 has negative refractive power and is made of plastic.An object side 662 of the sixth lens 660 is a convex surface and animage side 664 of the sixth lens 660 is a concave surface, and theobject side 662 and the image side 664 are both aspheric. The objectside 662 has one inflection point and the image side 664 has oneinflection point. Hereby, this configuration is beneficial to shortenthe back focal length of the optical image capturing system so as tokeep the optical image capturing system minimized. Furthermore, theincident angle of the off-axis rays can be effectively reduced, therebyfurther correcting the off-axis aberration.

The IR-cut filter 680 is made of glass, and disposed between the sixthlens 660 and the image plane 690, and does not affect the focal lengthof the optical image capturing system.
